This article is designed to equip R&D scientists, formulators, and procurement managers with comprehensive information on MTT's properties and its diverse applications, emphasizing the importance of sourcing from reliable manufacturers, especially those based in China.

Key Properties of 3-Methylthiazolidine-2-thione (MTT)

3-Methylthiazolidine-2-thione is a heterocyclic organic compound with a molecular formula of C4H7NS2 and a molecular weight of approximately 133.24 g/mol. Its characteristic properties, as reported by various manufacturers and suppliers, include:

  • Appearance: Typically presented as a white to off-white crystalline powder.
  • Purity: High purity is generally specified, often ≥98.0% or ≥99.0% by assay (e.g., HPLC).
  • Melting Point: Possesses a relatively low melting point, typically in the range of 65-70 °C. This facilitates its dispersion in rubber compounds.
  • Density: Reported densities are around 1.30-1.39 g/cm³.
  • Solubility: Soluble in organic solvents like toluene and methanol, with limited solubility in water.
  • Stability: Stable under recommended storage conditions (clean, dry, cool place, away from sunlight and rain).
  • Assay: A high assay indicates consistent product quality and reliable performance in applications.

These properties collectively make MTT a versatile and effective additive in various industrial processes.

Diverse Applications of MTT in Industry

The primary application of 3-Methylthiazolidine-2-thione lies in the rubber industry, where it serves as a potent accelerator for vulcanization. Its efficacy is particularly noted in the processing of specific elastomers:

  • Chloroprene Rubber (CR): MTT is widely recognized as a highly effective accelerator for CR. It contributes to achieving optimal cure rates, excellent physical properties, and good aging resistance in CR-based compounds, making it suitable for demanding applications like cables, tapes, and hoses.
  • Chlorobutyl Rubber (CIIR): For CIIR, MTT is a key component in vulcanization, enhancing cross-linking and improving the mechanical properties and durability of the final rubber products.
  • Bromobutyl Rubber: MTT is also suitable for use with bromobutyl rubber, facilitating its vulcanization and cross-linking.
  • General Rubber Compounding: Beyond these specific elastomers, MTT can be utilized in a broader range of rubber formulations where its accelerating properties are beneficial for achieving desired processing and performance characteristics.

The compound's ability to cross-link halogen-containing polymers stems from its active sulfur atoms, which participate in forming robust cross-linkages between polymer chains. This leads to improved resilience, heat resistance, and overall longevity of the rubber articles.
